Inversion trauma of the ankle.

By means of a questionnaire, an inventory was made of the residual complaints and possible handicaps 9 months post-injury in 1012 patients who had been treated for distortion or lateral ankle ligament injury. The response rate was 81% and responses were equally distributed among the various grades of distortion. Residual complaints were reported by 30% of the patients. The injuries were classified into three grades. For all grades, the nature and frequency of the residual complaints were the same. Explanations for the study results or guidelines for treatment cannot be derived from this study.
